The horrific shooting at Sandy Hook Elementary School in Newtown, Conn., has left a grieving nation in shock after a man gunned down at 26 people Friday morning, including 20 children.

The massacre has once again fired up a charged debate about gun control and thrust it into the national spotlight as celebrities sound off on the hot-button issue—a collective burst of anger, disgust and frustration.

Rashida Jones "Gun control is our only road to freedom. Freedom from the fear of senselessly losing children. I'm so saddened. WE NEED LAWS NOW...Gun loversare the first to remind you this should be a 'day of mourning'. How about we mourn & make it harder to get guns on the same day?...Thanks, gun lovers, for all your hateful tweets. Good reminder of another endemic nat'l issue:a lack of humanity, civility & accountability."
